succeeding carriers are connected in similar I manner, so that the said carriers travel as above. specified.

The fruit is fed to the first carrier, by means of a feeding chute 24c flaring toward the end remote from the frame, and the upper face of the said chute is provided with a series of trough-shaped grooves or passages 25, in which the fruit travels. A checlr plate 245 is arranged above the feeding chute, near the delivery end thereof, for preventing more than one member of the fruit from rolling onto the grading carrier at a time from each passage. The plate A is mounted in guides at, and may be moved vertically for large or small size fruit. The passages 25 are V-shaped, and the under edge of the plate 243 is recessed, as shown at each passage.

Strips 26 are arranged longitudinally of the carriers, above the upper runs thereof, and the under edges of the said strips are, notched or recessed, as shown at 27, to tolgrading carriers. The said strips 26 are arrangedin alinement with the divisions between the passages 25 of the feed chute, so that the fruit as it is fed, is separated into a number of subdivisions, five in the present instance and the fruit in each division remains separated from the fruit in the other subdivisions throughout its travel, or until it is discharged from the carriers.

Between each adjacent pair of rollers S and 16 a chute 28 is arranged, the said chute being supported at one end by standards 29 on the upper bar 2, and each of the said chutes 28 delivers at the opposite end from the standards 29 outside of the frame, as shown in Fig. l. The said chutes 28 have flanges 30 at each side to prevent the escape of the fruit, and each chute delivers onto a packing table 31. A chute 28 is thus provided for each carrier, as is also a packing It will be noted that one of the flanges of each chute 28, namely the one adjacent to the roller 8 is curved, so that the free edge thereof is adjacent to the free edge of the adjacent apron 13. As many carriers may be used as may be desired or necessary, and the grading device may be driven by any suitable form of motor. The belts 19 are of suitable material and are from one and one-half to two and one-halt inches in width, and are placed at differentdistances from each other in the various carriers. As for instance in the first carrier, the belts are spaced at intervals of two and one-fourth inches, and in the succeeding carriers they are spaced at intervals oi two and one-half. two and three-fourths. and three inches respcctively.

As a rule four carriers are made use of. The slats 11 are preferably of wood, and

noeneee are one and one-fourth inches in width,-but it is evident that they may be of metal or even. of belting if desired. The slats are spaced at the same intervals in the respective carriers as the belts, so that in each carrier perforations or openings of equal size are provided. The bearing plates 3 and 4 are pivoted to the lowermost bar l,as indicated at 32, and each bearing plate is engaged at its upper end by an adjusting arm 33, pivoted to the uppermost bearing plate, as indicated at 34. The said arms hold the upper ends of the bearing plates 3 and 4t properly spaced with respect to the rollers 9, and by pressing the free ends of the said arms downward, the belts of the carriers and the belts 18 may be tightened.

El e fruit to be graded, as for instance apples, is fed onto the feed chute 2e, and rolls down the sameon to the slats and belts of the first carrier. It will be noted from an inspection of Fig. 1, that the spacing or dividing strips 26 are arranged directly above the longitudinal center or" the belts 10, so that the openings or" the carriers are between the adjacent strips. As the fruit passes onto the first carrier, all of the said fruit that is below a certain predetermined size, namely of less diameter than the width of the openings between the belts, and the slats,"will fall through the'said openings onto the delivering chute 28 beneath the upper run of the said carrier. The said chutes are arranged between the runs of the carriers, and they are of such width, that they extend between the rollers 8 and 16. All of the fruit that passes through the first belt will be delivered to the first packing table 31. All of the fruitthat is above the size of the opening of the first carrier will i be delivered to the succeeding carrier, an the upper runs of the belts 18 will gradually raise all of the fruit above the level of the lower surface of the belts 10 before the said fruit reaches the roller 9.

The endless belts 18 are for the purpose or raising the fruit from between the slats, as shown in Fig. 3. Thus apples for instance that are of but slightly greater size than the openings of the first carrier will artially pass through the said openinga and the said apples might be in ured were there no means provided for releasing them from this position before they engage the roller 9. \Vhen the fruitpasscs onto the second carrier, all of the fruit that is of less diamctcr than the width of the openings of the said second plate will drop through and the process will be continued until the grading is completed.

VVith the openings spaced as above menti oncd, apples below two and one-ztourth inches in diameter will be delivered to the first packing table. Apples below two and one'half inches in diameter will be delivered able manner ing carrier at the lower memes to the second table, apples below two and three-fourths inches in diameter will. be delivered to the third table, and below three inches in diameter will be delivered to the fourth table. All apples above-three inches in diameter should there be any of this size, will bedelivered at the end 0 the last car rier.

As the fruit passes from each carrier to the succeedingcarrier, it is delivered onto t1e apron 13, and each of the said aprons is inclined so that the fruit will slide down the same onto the upper run of the succeedend thereof. The delivering chutes 28 incline downwardly toward the packing tables so that the fruit will travel of its weight. 4

The grader may be operated in any snitand from any suitable source of power, as for instance by means of a belt connecting the source of power with a pulley 15 on the shaft of the first roller 9.
